Boilers and Water Heaters

DB Sales has been selling, installing, and servicing  boilers in Los Angeles, Orange County, and San Diego areas since 1978;our expertise will help you make the best selection for your specific application needs. We have recently added a boiler rental service.

When adding new parts, equipment, and technology to a boiler, the goal is to increase the efficiency of a system. New advancements and design improvements allow an older unit to increase its potential. Since most boilers only operate at around 60%, replacing or retrofitting of an older boiler could equal huge cost savings for a company.

An average boiler can consume almost four times its cost every year in energy. Enhanced function of a new or retrofitted boiler saves fuel and improves the quality of overall output. Finally, a boiler that has been replaced or retrofitted reduces the emission of carbon and other pollutants into the air.

We work with a wide variety of boiler manufacturers to offer you a broad spectrum of boilers and water heaters, including high-efficiency modular boiler systems, hot water boilers, steam boilers, electric water heaters, and electric boilers in Los Angeles, San Diego, and Orange County.

Boiler Installation and Commissioning

DB Sales is highly experienced in all aspects of boiler system management, including steam, hot water, hot oil and electric boilers, and all related equipment and accessories.

If you need new equipment, we assist you with the requirements for planning and equipment selection. Our company represents a wide variety of manufacturers of boilers and auxiliary equipment. We also support you with the installation planning layout, installation and commissioning process.

Rebates for Boilers

DB Sales is an expert in energy efficient equipment rebates. We work with all our customers to identify potential rebates for boilers in Los Angeles, Orange County, and San Diego areas. Then, our team will source and install burner and control systems to retrofit existing boilers to meet ultra-low NOx emission standards.

“We Take Water Heaters Very Personally”

DB Sales has recently added Bock Water Heaters to its lineup. The addition is in alignment with DB Sales emphasis on energy efficiency, quality, and value in heating and cooling products. Bock Water Heaters are engineered to handle a wide range of heating loads while using minimal energy inputs. They are more robustly engineered than those in their class—the walls are thicker and they have a corrosion protection system. Bock products are designed to last a long time while minimizing expenses.”

These water heaters have features in four key areas that are important to DB Sales clients, including:

  • Greater Energy Savings – modulating pre-mix blue flame burner reduces fuel consumption by 15% to 25% compared to non-modulating condensing or conventional water heaters
  • Reliability and Durability – heat exchanger-to-tank weld joints are overlapped and double-wall reinforced
  • Less Maintenance – automated cathodic corrosion protection system with no sacrificial anode rods
  • Higher ROI – up to 97% thermal efficiency and minimal maintenance

About Bock Water Heaters
Founded in 1929, Bock Water Heaters is North America’s largest manufacturer of oil-fired water heaters and a leading producer of commercial gas water heaters. Today, Bock Water Heaters manufactures water heaters designed to operate on any fuel (solar, geothermal, natural gas, propane, oil and electricity) and offers a large portfolio of indirect water heaters and storage tanks, such as:
